Called ahead of time to get info on "best burger I ever built." Phil's does not have a gluten-free bun. Guess I'm not building a buger at Phil's. I forgot my Local Oven hamburger buns back in TX. (Individually wrapped. Pretty fluffy at room temp. Heat does enhance a LO bun, but not required. Owner Linda. F. is a good friend of mine.) -Sheri T. @ourgfadventures on Twitter
